Abstract
The invention resides in a process air dryer system for plastics processing machines and method for drying process air comprising two desiccant towers repeatedly alternating between process and regeneration cycles. In addition to conventional bottom heaters, each tower has an additional generally central heater so as to reduce the time required to regenerate saturated desiccant. When a tower is undergoing regeneration of its desiccant, generally centrally heaters aid conventional bottom heaters in drying saturated desiccant so as to reduce conventional regeneration cycle time by as much as 25% to 30%.
